i done all the recent mods to the 12v quantizer that were listed in the thread on this forum R1 ... 120K changed to 200K etc.
and it seems to be working ok on half notes around the middle of the keyboard range , alot of folk that do the 15V version seem to have probs , but ive not had it hooked up to my 5 count multimeter recently , tho i'll probly not use it much , i'm adept at ear tuning with the fine controls .

There is just enough room to get my finger operating the gate switch without knocking the coarse tune , phew

Hi Dave
build is looking good
quick question
what is the overall size of your panel ?
I have 2 to do on my list and with a feature set exactly the same as your build so your panel layout looks like a good point to work from.

Hi Diablo

Thanks.

The size of the aluminium is 400mm W x 250mm H.
my single modules are all 100mm W x 250mm H.

The staggered strips of step control was the only way i could comfortably fit it in , tho when the seq is running i do a nodding head when my eyes follow the led's , up down up down

Good luck with your build , and take your time , planning is essential on this one.

cool that may work well then
I build in 2 sizes
483mm high by 50mm wide increments for my large cabinets
and
241.5mm high by 50mm wide increments for my smaller cabinets_________________In an infinite universe one might very well
ask where the hell am I
oh yeah thats right the land of OZ
as good an answer as any

Ashley ... DaF i have an old mini album by them in my record collection "Fur Immer" i think , recorded by conny plank in 1982 , kinda sets the studio ready for "some great reward by Depeche Mode" a couple of years later , good sounds on the DaF album _________________epicyclus@skrogmusic.plus.com

HI Skrog, perhaps you can help me with the integration of my 16 step sequencer with variclock quantized sequencer add, i put a new topic but there are not answers, perhaps you can help me, i decided add the project to my old sequencer

HI to all I made the integration of the sequencer variclock with my rotary design panel, courtesy of Thomas White and wonderfull design of Mr Ray Wilson, amazing sequence.
I have a few problems and I expose in the forum to Ray or somebody can help me.
Ok the main problem is that, I have no variclock quantize, I put the sequencer in Step Mode but when I move the pots of the variclock, it doesn’t work, the four leds of the quantize lits in the same place, there is not change. I try with the trimmer but I can´t see changes in the leds. I am using +/- 15V
For example if I turn off the sequencer and turn on, the leds lit in other combination, for example turn on: 1 1 0 0, turn off and on again and now I have 1010, again 1011, etc, always randomized.
I have not a 2 nf capacitor and I put X2 1nf in parallel for Capacitor C4, but I think this is ok. Am I wrong?
I cut the ABCD cables of the analog and digital pcb and I soldered all the cables in parallel abcd in the correct order with the variclock pcb, I trace with multimeter and ABCD of analog are connected with ABCD of variclock, the continuity it’s ok. I have +15 volts in all the pots connected to +15V rail, and ground its ok too, the x8 to x29 and x7 to x25 are connected ok with the new pots in the correct order.
I check all connections of the variclock pcb with the new and old components and wiring panel, it’s all ok
Check list
Components To Remove
• R18 (20K resistor)
• R23 (6.2K resistor)
• C10 (1uF capacitor)
• D9 (1N914 Diode)
• R43 (3.9K resistor)
• R41 (1K resistor)
• R24 (3K resistor)
• R42 (1K resistor)
• LED1 is no longer used.
• R19 (1M Clock Rate Adjust pot) is no longer used. (I let the old r19 in same place and change the connections to x34 and x4
Done

terribly sorry i've not dropped in , been distracted by astrophotography and a rare spell of clear nights .

Hi , fault finding on this add-on is very hard to do remotely via the net , mainly because the add-on pcb requires some mods to the main sequencer pcb.
Single pcb projects are usually easy to de-bug, but this involves 3 pcbs and mods to the existing sequencer , all we can suggest is do the usuall basic checks to the wiring , component values , orientation , and power connections , other than that re-read the instructions over and over again to see if they correspond with what you have wired up & built so far , it may take time but you will eventually find the problem , with the amount of new wiring involved it really is like looking for a "needle in a haystack"

Best of luck , this add-on requires a fair bit of thinking / planning and is not to be rushed , start at the begining and go through all your work , somewhere along the way a lightbulb will illuminate and a sense of revelation will come over you

heyyy, sorry for the late answer, i didn't see the post, thanks a lot for answer me, ok i have to recheck all the schematics and cables, i think i will find the the error, at last always fail the humans, not machines.

I'll try tonight with a 12v PSU. I'll tell you wath happening. I sent mail to Raymond ADN hé sait me that hé didń´t test the vari clock module with a 15v PSU and then maybe There are some resistor values to change

I'm still having a problem with getting binary state 0001 to latch , i can select 1 step count also 3 counts to 16 with correct leds lit , i just can't seem to get 2 step counts, i'll try again over the weekend.

Had another study of the schematic and read Ray's scope photo's section text, he says...... "observe U1-A pin 2 , must be approx 54Khz" , mine was 77Khz , i popped out one end of R26 (20K) (A to D clock section) and temp. hooked up a 50K trimmer in series to try some adjustments , adjusted so the meter read 54Khz , cool latching on LED 1 now , hmmmm now i have no saturation point , LED 1 on at ground where 0000 should have no LEDs lit , ok try uping the frequency (using that temp trimmer , giving a new total resistance of 6K2 + the 20K , R26 now = 26K2) , this got the freq. to 58Khz and the span is working great even with my rotary switch set up .

Quick ... screw it back into the modular and resume music making, hehehe

I just built one of these over the weekend and I'm having a whole host of problems with it.
- The frequency pots fully counter clockwise are at a high frequency. as they are turned clockwise they get lower and then swing up again just before getting fully clockwise.
- The leds for the change frequency as they blink
- It will only run with the quantized clock selected, and the lowest I can get is 9 clocks per step.

Probably some other stuff I have yet to discover. Really not looking forward to combing over this one. Any suggestions are most welcome.
